Application filed April 12, 1913.

Patented Jan. 6,1914. Serial No. 760,730.

' siding at Pontiac, in the county of Oakland and State of Michigan, have invented certiun new and useful improvements in Gunpowder and Processes of Making the Some,

of which the follow ng is a specification.

My invention relates to explosives and has particular' reference to gunpowder and the process of makingthe same.

An important object of this invention is to produce gunpowder having a great explosive force or strength and which is safe to use in ammunition.

The composition of my explosive or gunpowder preferably consists of the following ingredients combined preferably in substantially the proportions stated, to wit: potassium chlorate, eight ounces; sugar, preferably granulated sugar, seven ounces; glycerin one drahln; and -water, two drahins.

In the practice of my process of making the explosive or gunpowder, T place the sugar, glycerin and wutelu preferably in the proportions stated, in a suitable recep tacle and heat the same while being stirred, until the mass boils. By this time the sugar is completely dissolved. No furtherheating of the mass is necessary; The potassium chlorate is then introduced into the mass and the same is thoroughly stirred. The linalniass or product is passed or bolted through a sieve or screen of a suitable gage to give. the proper grain to the resulting powder. By the time the mass has been passed through the sieve the same is practicelly dry, at least sufficiently dry so that the grains of the same will retain. their individuality.

portions of the ingredients are to be taken as a preferred example of the invention, and that such proportions may be widely varied with some degree of success and without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention, I claim:

1. An explosive composition comprising substantially eight ounces of potassium chlorate, seven ounces of granulated sugar, one drahrn of glycerin and two drahms of water.

2. The process of producing an explosive composition, which consists in dissolving sugar in a solution of glycerin and water by heating the solution until it boils, and subsequently introducing potassium chlorate into the mass thus obtained While heated and below the boiling point and thoroughly stirring the same.

3. The process of producing an explosive composition, which consists in adding sugar to a solutum of glycerin and water, heatin the mass unit] it boils and dissolving the -sugar in the heated solution by stirring it,

adding potassium chlorate to the mass thus obtained while the mass is heated and at temperature below the boiling point and thoroughly stirring the same until the potassium chlorate is dissolved, and passing the final product through a sieve, for changing the game into a granular mass.

In testimony whereof I atlix my signature in presence oi two witnesses.
